About this book

The book explores the science of extreme longevity in the natural world, examining plants and animals that have lifespans far exceeding human expectations. It features specific examples like the 80,000-year-old Pando aspen colony, 11,000-year-old deep-sea sponges, and 400-year-old sharks. The text explains the technologies scientists use to determine age, including DNA sampling, growth rings, and radiocarbon dating, and investigates how these organisms resist disease and aging.
